To all whom 'it may concern:

Be it known that I, CHARLES PARSONS, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Rail-Joints, of whicht-he following is a specication.

This invention relates to rail joints, and has for its obi ect toprovide an improved rail joint in which the fish or side plates areformed integral with chair plates on which the rails rest, with meansfor increasing the grip of the plates against the rail, increase of loadbeing followed by an increased pressure or grip of the plates on therail, this grilp being most effective on the base of the ra Theinvention is illustrated in the accompanying drawings in which- Figure 1is a perspective view of the joint. Fig. 2 is a vertical cross section.

Referring specifically to the drawings, the rail ends are indicated at land 2. The fish or side plates 4 are made integral with the chair orbottom plates 5, the lower edges of the sh plates being connected to thechair plates by means of a thickened, curved por-l tion 5a which isshaped or bent to extend around the edge of the base of the rail, arecess being formed in which the base of the rail fits. The parts areattached to the rails by the usual bolts 3.

The chair plates 5 are shaped on the upper side to produce alongitudinally extending raised portion l2 which projects above theremainder of the plates and forms a contact line on which the railrests, said lines of contact being about midway between the edge of therail base and the middle thereof. At the lower edge the fish plates areenlarged or shaped to form an inwardly projecting rib or line of contactindicated at 11, which contact with the rail at the angle wherelthe webjoins the base, pressing inwardly and downwardly upon the top of thebase. The two sections of the joint are united under the rail by meansof an upwardly projecting lip or hook 9 formed along the edge of oneplate which is engaged by a downwardly projecting lip or hook 10 formedon the edge of the other plate, and adapted to prevent lateralseparation of the parts. The upper edges of the sh plates bear under thehead of the rail. The two parts of the joint thus formed have a certainamount of spring, and originally are so rolled or shaped that thepressure of the bolts 3 is necessary to draw the sh plates togetheragainst the web of the rail. Then they are so drawn together the stresscauses the contact points 1l to bear downwardly and inwardly at the baseof the web of the rail, and the contact points l2 bear upwardly, theparts being otherwise out of contact with the base of the rail. Thisproduces a joint or grip on the rail base. When the pressure on the railis increased, as by a train passing over the saine, the force exerteddownwardly on the points 12 tends to turn the upper parts of the ointinwardly, increasing the pressure along the points 1l and causing thefish plates to increase their grip on the ends of the rails; and thegrip increases as the pressure increases, which is decidedlyadvantageous for the purpose of holding the joints securely andpreventing looseness or pounding at the joint. The parts are attached tothe ties 8 by means of spikes G engaging lips 7 projecting from theouter edge of the chair plates or parts.

The connection between the parts or sections formed by the hooks 9 and10 is sufficiently flexible to allow the slight turning action which inconsequence of the leverage ca uses the fish plates to bind tightlyagainst the rail ends when a train is passing thereover. The joint alsohas the advantage that the parts can be separated by removing the bolts8 and the spikes and lifting the rails slightly and turning the sectionsto disengage the hooks, the recesses in which the rail base fits beingsufficiently large to permit this action.

I claim:

l. A rail joint comprising-two separable sections each consisting of afish-plate and a chair-plate integral therewith, the chair plates beingflexibly connected under the rail, and each having a longitudinal rib onwhich the rail rests, said ribs being spaced from each other, and aportion extending over and bearing upon the top of the rail base andconnected to the fish-plate.

2. A rail-joint comprising two sections connected together under therail base, each consisting of a part forming a fish-plate, a partforming a chair-plate, and a connecting part extending from the loweredge of the fish-plate to the outer edge of the chair plate, the chairplate having a longitudinal rib on the top and the connecting partbearing against the rail base at its angle with the web of the rail, theline of Contact of the rib being outside of the line of said bearing.

3. A rail joint comprising two sections each consisting of a fish plateand a chair plate integral therewith, the chair plates having hooksengaging each other under the rail base and each having a longitudinalrib 0n the top forming a Contact line on which the rail base rests, theish plates having ribs contacting with the top of the rail base adjacent the web of the rail.

4. A rail joint comprising two sections, connected together under therail base, each consisting of a fish plate hearing at its lower edge onthe rail base, and a lower part integral with the fish plate andconnected to the lower edge thereof, said lower part being thickened andcurved around the outer edge of the rail base and extended under saidbase to forni a chair plate, forming a recess to receive the rail baseloosely, the chair plates having spaced ribs extending along` the topthereof on which the rail base rests.

In testimony whereof, I aiiX my signature in presence of two witnesses.
